ABRADlNG-COVERING FOR BU FFERS.

SPECIFICATION forming part of Letters Patent No. 407,249, dated July 16, 1889.

Application filed December 7, 1885- Serial No. 292,927 (No model.)

To a6! whom it may concern: also,awaste of material in forming the cover- Be it known that 1, ANDREW W. ROGERS, ing. Coveringshave also been formed as in the of Beverly, in the county of Essex and State patent of Trask, granted by the United States of Massachusetts, have invented a new and Patent Office in 1887 No. 864,688, in which 5 useful Improvement in Abrading-Coverings theedge of the covering is turned up at inwith Attaching-Strips for Buffers and I do tervals in indented portions of the edge, and, hereby declare that the following is a full, as is well known, coverings have been used clear, and exact description of the same. on such buffers in the form of pouches.

I have shown only four of these strips edge of the buffer-foot, formed a pouch and attached to or near the margin at-equal disheld the covering to the foot; but all these left tances apart. They are attached to the disk I00 50 turned-up abrading portions exposed on the by gluing to the inner surface with the ends margins likely to mar the heel and involved, projecting upward, and when another disk or re-enforcement is fixed to the inner face of the abrading-disk the ends of the connectingstrips are inserted between the re-enforccment and the abradingdisk. \Vhen the covering is in place, the straps are turned up over the edges of the foot, and may be secured thereon in any convenient manner. As shown, they are held between the upper face of a base I) and the lower face of a clamp E; but these form only one of many well-known means for holding such connections. Thus turned outward and upward the strips fit snugly over the edge of the foot, which with these requires no notehing or holes.

The re-enforcing disk may be of slightly less diameter than the sand-paper, in which case the strips are turned up on the edge of the re-enforcement, and are consequently a little back of the edge of the sandpaper, and this may be in some cases an advantage; but where both sand-paper and re-enforeement are of the same diameter and the edge of the disk coincides evenly with the edge of the foot the flexible strips are drawn so closely to its face that practically no obstruction is offered by them in working. Their flexibility causes them to yield with the yielding foot, with which they are commonly used, and the buffer provided with these coverings will work on any part of the surface of a boot or shoe sole.

\Vith the flexible strip as above described I am also enabled to use a double-faced covering by simply using an abrading-disk as a re-enforcement, its abrading-surface being on the upper side. This is shown in Fig. 4. In

this the covering is composed, in fact, of two disks of sand-paper or emery-cloth A A, of the same dlameter, placed back to back and glued together, with the ends of the strips held between them. One thickness acts as a re-en forcement and stiffcns the other, and the covering may be used with the same eil'ect with either side out, the edge of both being formed by cutting out the disks from the sheet and having them unsanded and nonabrading. In every case this non-abrading edge of the covering does not require turning up in any part, and is left exposed to work closely against the heel. I do not herein claim, broadly, the reversible covering, and here expressly disclaim the matters claimed by me in applications filed by me of even date herewith and having the serial numbers, respectively, of 292,924 and 292,925.

I claim as my invention 1. An abradin g-coveri n g forbuifers, consisting of a disk having an abradingsurface and non-abrading edges and flexible non-abrading connecting-strips secured to the inner face with the free ends projecting outward, substantially as described.

2. An abrading-eovering for buffers, consisting of a disk having an abradiug-surfaee and non-abrading edge, a re-enforcement on its inner face at or near the edge, and flexible non-abradingconnecting-strips secured to the inner face between the abrading-disk and the re-enforcement with the free ends extending outward, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
